6 Claims. (01. 126-214) This invention relates to improvements in meansfor protecting the burners of gas stoves from the overflow of boilingpots and cooking vessels, and its leading object is to provide a safetyprotecting plate which can be placed over a gas burner, and which willallow the heated air to flow upwardly, and cause the water which boilsover to drain away from the flame jet openings of the gas burner.

Another object of the invention is the provision of a safety protectingplate for gas burners, which will concentratethe flow of the waterdischarged from a cooking vessel when it boils over, toward the centerof the gas burner and por- 15. tions of its radial wings, so as todirect the drainage away from the jet openings of the gas burner, so asto prevent the water from the boiling cooking vessel from extinguishingthe burner-flame. t

A still further object of the invention is to provide a top plate forgasstoves, which will provide complete safety against the accidentalextinguishing of the burner flames by the water which boils over fromcooking vessels, and which can be placed in position by any housewife01' other person.

With the above and other objects in view the invention consists incertain new and useful combinations, constructions, and arrangements ofparts, clearly described in the following speciflcation, and fullyillustrated in the accompanying drawing, in which:- 7

Fig. 1 is a plan view of the improved safety plate.

Fig. 2 is a transverse sectional view thereof, taken on line A of Fig.1, looking in the direction of the arrow,

Fig. 3 is a plan View of a stove plate embodying a plurality of sectionseach having the pro- 40 tective features.

Referring to the accompanying drawing illustrating the practicalconstruction of the invention 5 designates a circular plate, which maybe constructed of stamped sheet metal, or cast in one piece fromsuitable heat resisting metal. When made from sheet metal the plate ispreferably formed with a U-shaped rolled edge portion 6, which presentsan upstanding marginal flow limiting rim, and an annular depending skirt6a, which is wider than the marginal flow limiting rim 7.

The plate is slightly dished from this marginal flow limiting rim '7toward the center thereof, and the center is formed with a dependingtubular outlet 8, which is designed to receive the overflow waterdischarged by the cooking vessel, which is placed overthe plate andwithin the marginal rim 7. 1

The plate is formed with radial openings or slots 9, spacedcircumferentially from each other, and the marginal edges of theseradial openings are provided with upstanding flanges 9a, of slightlyless height than the marginal rim 7. The openings are shown triangularin form, but any other desirable shape may be used.

outwardly of the radial openings'and their flanges arcuate vesselsupporting flanges or beaded portions 10 are formed, the opposing ends'of which are spaced apart to allow nor- '(0 mally open drain channels10a, to permit the overflow water to flow between the flanges 9a anddischarge through the central outlet tube 8, and to discharge over thegas burner, at a point safely remote from the jet openings of theburner, from which the gas flames are fed. The radial imperforateportions 9" are designed to register at the radial flanges of a standardgas burner, which are thereby protected from filling up from thedrippings of grease or carbon particles deposited from the bottom ofpots or other cooking vessels, while the radial openings 9 are designedto register with the spaces between the radial flanges of a standard gasburner, thus permitting a free circulation of heated air from the gasburner under the pot. The central openingoutlet 8 is adapted to registerwith the central opening of a standard gas burner and thereby centersthe safety plate with reference to the gas burner.

The upstanding circumferential flanges 10 support the pot upon theflanges 9a, so that the heated air flowing over the gas burner can flowthrough the openings 9 and through the channels 10a to dischargeoutwardly of the sides of the pot as indicated in Fig. 2. 'By thisconstruction the safety device provides for ample circulation of theheated air and at the same time afiords a centralized drainage of anyoverflow from the pot, while at the same time maintaining lOO a separatepath for the flow of the heated air at any time during an overflowingmovement. This effect develops from the fact that the overflowing waterwill drain on the inclined surface of the plate and the heated air candischarge above 105 the surface of the water through the openings 9 andthe channels 10a.

In Fig. 3 I show a stove plate or covering 11, which is formed withthree integral safety protecting plates, 12, 13, and 14, each embodyingl10 the principles of construction shown in Figs. 1 and 2.

This combined stove plate and burner protecting device may be attachedto gas stoves at the factories where they are made, or may be attachedby the individual user. The combined stove plate and burner protectingdevice may be constructed with two, three, four or more protectingplates in any arrangement desired to match the burner assembly of a gasstove.

In the use of the safety plate a slight overflow will drain through thechannels or passages 10a into the central outlet 8, while a greateroverflow will pass over the flanges 9a into the openings 9, anddischarge over the gas burner,. away from the jet openings thereof.

The openings 9 may be arranged according to any desired plan, to matchthe radial. dis-.7

position of the flanges of any particular gas burner, so thatthe saidopenings 9 will be opposite the space between adjacent burner flanges,while the imperforate portions 9' be tween said openings 9 will lieopposite the flanges of the gas burner.

The cover top 11 is also formed with arcuate openings 15, locatedoutwardly of the safety portions thereof, and adjacent thereto, topermit the heated air to flow upwardly, so that fresh air will flowtoward the burners and efficient heating of anycooking vessels disposedon the improved stove cover or top will result.

Having described my invention I claim:-

1. A safety plate for gas burners consisting of a plate adapted to covera gas burner and provided with an inclined draining surface surroundedby a flow limiting element and discharging into a drain outlet andprovided with radial openings spaced to; register with the spacesbetween the flanges of thegas burner.
